Abstract

Scarcity of fresh water has led to use of low quality waters (high sodicity and salinity) that were considered unsuitable for irrigation in the past. Mismanagement of irrigation using this water can increase the potential for soil degradation and limit crop production in the
long-term. Irrigation using highly saline-sodic water requires appropriate management to avoid long-term development of sodicity and salinity problems. The main factors that control the sodicity and salinity problems are maintenance of sufficient leaching and avoidance of soil structure degradation due to sodicity. However, the management options are determined by complex factors such as soil type and condition, water quality, irrigation practice and crop type. The fundamental processes occurring within soil profile under irrigation with highly saline sodic waters, and the problems related to salinity and
sodicity in the soil-water-plant system are complex. Modelling is an efficient tool to quantify and manage these problems. However, there has been limited research in
modelling of irrigation under highly sodic and saline conditions.
